Test method for spectrometers and spectrometer with a test function

摘要

a test for the functional testing of a spectrometer with a sendeeinrichtung for production and transmission of radiation in accordance with a predetermined wellenlu00e4ngenverlauf, a probenaufnahmebereich, through which the radiation caused by,a erfassungseinrichtung for recording by the probenaufnahmebereich led radiation and to generate a signalspektrums depending on the collected radiation and a auswerteeinrichtung for evaluation of the signalspektrums,test steps comprises the following: modification of the radiation intensity in accordance with a predetermined pru00fcfreferenz in the spectrometer through a modulationseinrichtung, generate an pru00fcfspektrums depending on of the modified radiationcomparisons of the pru00fcfspektrums with one of the pru00fcfreferenz assigned erwartungsspektrum and identification of accuracy or a fehlerzustandes of the spectrometer as a function of deviations of the pru00fcfspektrums of the erwartungsspektrum.
